A system and method for ECG electrode and leadwire connection integrity detection are provided herein. The system includes a plurality of electrodes wherein a uniform spectral energy signal is to be injected into a subset of electrodes of the plurality of electrodes. The system also includes a computing device. The computing device includes a display, and the computing device is communicably coupled to the plurality of electrodes. The computing device is configured to acquire input signals from an electrode and determine a frequency response from the electrode based on the input signal from the electrode. The computing device is also configured to determine impairments in the electrode and leadwire connection using the frequency response.

ECG electrode and leadwire connection integrity detection

A medical diagnostic/monitoring system is disclosed herein. The medical diagnostic/monitoring system includes a data acquisition device having a first near field communication device, and a data storage device wirelessly connected to the data acquisition device. The data storage device includes a second near field communication device. The first near field communication device and the second near field communication device are collectively configured to wirelessly transfer power and data from the data acquisition device to the data storage device.

Apparatus and method for wirelessly transferring and storing medical data

Devices and methods comprise or provide an ECG recording device containing a mailable base and electrode assembly and/or other means engageable with the base to receive ECG signals from a subject during a self-administered ECG examination. The devices and methods may also include a single-use or limited-use ECG recording device, in which the base is disposable or reusable or recyclable. In addition, the device may be self-contained, battery-operated, portable, disposable, mailable to a location remote from an ECG examination, provide feedback, indicate its method of use, including graphically depicting same, contain a finger cuff and/or sensor pad for receiving ECG signals, and/or contain a memory. Preferably, the base conforms to various body shapes and/or sizes, is made of flexible and/or semi-flexible material, and/or contains a receptor, such as sealable blood well. The device can also communicate the ECG signals to an ECG processing system, which can be remote from the ECG examinations and comprise wireless communications.

Devices and methods for self-administered ECG examinations

The system and method of the present application includes an ECG acquisition device having a USB connector for connecting the device to a host device and a patient connector for connecting the device to a patient with ECG leads. The ECG acquisition device of the present system further includes a processor and storage medium, a power management and brokering module, a USB communications control module, an ECG acquisition circuit, and a patient isolation module. Unlike prior art ECG acquisition systems, the system of the present application affords a truly portable ECG acquisition device that may be connected through the USB connector to any host device having software processing capabilities and a display. The ECG acquisition device auto-loads and runs ECG monitoring software onto the host device eliminating the need to install additional acquisition software and/or drivers to the host device, and allows the acquisition device to interface with a host device of varying platforms.

An exemplary embodiment of the invention is a method for analyzing product delivery to customers. The method includes generating a first level product classification corresponding to a number of products and determining delivery data for the first level product classification. The delivery data includes a span value indicative of delivery error for products in the first level product classification. The first level product classification is divided into at least two, second level product classifications. Each second level product classification corresponds to a subset of the first level product classification. Delivery data is determined for each of the second level product classifications. The delivery data includes a span value indicative of delivery error for products in the second level product classifications. Other embodiments of the invention include a system and storage medium for implementing the method.

Method, system and storage medium for analyzing product delivery

An apparatus and method for controlling a motor/blower system to provide a constant fluid flow by iteratively loading revised stator frequency values and stator voltage values to a variable frequency drive. Target DC bus current values corresponding to constant fluid flow rates are predetermined and stored as a function of the desired fluid flow rate, the operating frequency, and system specific constants or calculated by the controller as a function thereof during system operation. Actual DC bus current is measured with a current sensor and compared with the target DC bus current. Operating frequency is estimated using a PI controller based on the difference between measured and target DC bus current values. Operating voltage values corresponding to operating frequencies and system specific constants are predetermined and stored in memory or calculated by the controller during system operation. An updated target DC bus current, operating frequency and operating voltage are determined upon each iteration. The updated operating frequency and operating voltage are loaded as control variables to the variable frequency drive upon each iteration.
